The sun is in fact. As stars age they get bigger,hotter and emit different color wavelengths. The older it is it gets bigger and turns more bluish. As it gets even older it collapses in on itself becoming really tiny and white. Our sun is yellowish orangish indicating that it is still very young.
mass
A supernova occurs at the end of a massive star's life cycle.
Protostar!
None at all/ The life cycle of a star is based on it's initial mass, not where it was formed.
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
It is approx half-way through its 10 billion year life cycle.
The size of the star

what is the third stage of the star cycle
Nebulae are associated with the end of a star's life cycle, as they are shells matter that blown off a star, usually in a series of events, when a star is in its death throws.
How does the life cycle of humans compare to the life cycle of a star? They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
Nobody "invented" it, the life cycle of stars happens naturally.
A dog.
